Thank your for your bug report. This seems to be the result of local misconfiguration, installing an unsigned kernel, and the script does exactly what it was supposed to do.
If you need help with your system, consider using askubuntu, ubuntu-users mailing list, the #ubuntu IRC channel on libera, or other user support channels.
